Integral with the yoke 42 is a segment 43 meshing with the teeth of a segmental gear is fastened to a shaft L5 projecting from the frame 37. Also fast on this shaft is an arm 46 pivoted to a link 47, which at its lower end has a. notch 48 cooperating with a pin 49 carried by a lever 50 secured to a shaft 51. Shaft 51 is given first a counter-clockwise and then a clockwise rotation on every operation of the machine as described in the above mentioned patent and with the parts in the positions shown in Fig. 1, it is clear that the link at? will be moved downwardly when the shaft 51 is rocked counter-clockwise. This movement of link 47' rocks the arm l6, shaft and segment gear 44 clock wise. The yoke 42 will, therefore, be rocked counter-clockwise a suthcient distance for the driving pawl 40 tomove the. units ratchet wheel 38 one step. As the lever returns to its normal position, the link 47 will be raised and the driving pawl will be returned to the position shown in Fig. 1.

Disabling consecutive number actuator by total Zcvcr Since it may be. undesirable to print a consecutive number when a total is. being taken,

mechanismis provided for automatically dis abling the consecutive. number actuator whenever the total lever is. moved out of its adding position preparatory to printing totals. This mechanism is shown and dement G6 isa. spiral pinion 5L fastened to a shaft 68 supported by the frame 37. Also secured tothe shaft 6Sis a segment 69 (Figs. 1, and 3), which cooperates with a roller 70 carried onthe right hand endo-f a pitman 71. The pitman 7 1 is pivotally connected near its right hand end to a bell crank lever 72 and at its left hand end, is bifurcated and cooperates with a pin 73 projecting from the frame 37. The pitman 71 also has a slot 74 formed'therein through which projects a pin 75 carried by the link 47. lVith the parts in the positions shown in Fig. 1, the link l'l' may be moved first downwardly and then up wardly withoutany interference. from the pit-man 7.1.

However, if the total lever is moved in either direction out of, its normal adding position, (shown in Fig. 3) the link 63 will rock thearm 64 andspiral segment 66 either clockwise or counter-cloclnvise, and. this movement, through the spiral gear 67 and shaft 68, will rock the segment 69 either counter-cloclnvise or clockwise, depending upon the direction in which the total lever is moved. lVhen the segment 69 is given this movement, the pitman 71 will be. forced toward the left, dueto the engagement of the roller with the periphery of the segment, and as the pin 75 on the link 47 projects through the slot 74 in the pitman TI, the movement of the pitman toward the left will carry the link with it. The link at? has a notch 78 formed therein which will then cooperate with the stationary pin 73. The notch 48, which is normally in engagement with the pin. l9 of the driving lever 50-. will be disengaged from said pin, and therefore, when the lever 50 is given its counter-clockwis and, clockwise movements, the link 417 will not be moved and the consecutive numbertype wheels will not be turned.

As this bell crank lever. is pivoted to the pitman 71, the pitman will. be moved toward the l ft and the consecutive number wheel-actuating mechanism will be rendered inoperative in the same manner as above described in connection with the movement of the total lever 60.

'The key is held in its normal undepressed position .by a spring 115 stretched between a pin on the bell crank lever 7 2 and a suitably located pin 116 on the machine frame.

The ineans for latching the key 111 in depressed position for a single operation only will now be described. The shank 112 has a shoulder 117 which norm-ally lies justabovea flattened pin .118 carried by a bellcrank lever 119 pivoted 'on the machine frame. The pin 11.8 is normally held incontact with the lower inclined edge 121 of the shoulder 117 by a spring 120 extending between one arm of the bell crank 119 and the pin 1116. When the key 111 is depressed, the inclined :edge 121 of the shoulder 117 will force the pin 118 outwardly until the shoulder 117 passes below the pin, whereupon the spring .120 will rock the bell crank .119 clockwise and move the pin .into position above the shoulder 117, thereby holding the key 111 depressed. As described in connection with thefirst form of the invention shown herein, there is a. shaft 96 which receives a counter-clockwise and then a clockwise movement near the end of every operationof the machine. Fastened to this shaft is an arm 122 which carries a pin 123 cooperating with an inclined surface 124 of the bell crank 119. It is apparent from Fig. 1 that when the shaft 96 is given its counter-clockwise movement near the end of the operation, the pin 123 will cause the bell crank 119 to rock counter-clockwise, due to-the engagement of this pin with the inclined surface 121, a suflicient distance to remove the pin 118 from above the shoulder 117 of the shank 112. The key 111 is then free to return to its normal undepressed position under the influence of the spring 115.

The following described aneans are provided for latching the keyinitsdepressed po sition during a plurality of 0 81Lt1OIlS, or until manually released. The s ank 112 has an opening 125 formed therein through which projects a stud 126 carried by the machine frame. This stud has a flattened side 127 on its under side. A shoulder .128 is formed in the wall of the opening .125 in such a position that if the key 111-is depressed and then moved sidewise with the shaft as a pivot, the shoulder will move beneath the flattened side 127 of the stud 1 26 and hold the key in its depressed position. It is evident that this position will be retained by the key until it is moved manually far enough to disengage the shoulder fromthefiattened side 12?, whereupon the sprin 115 will .raise the the key to its normal, undepressed ,position, upon a subsequent operation of the machine during which the arm 122, through stud 123, rocks the bell-crank 119.,to release the key.

While the form of mechanism hereinshown and described is admirably'adapted to fulfill the objects primarily stated, it is to be understood that it is not intended to confine the invention to the one form or embodiment herein disclosed, for it is susceptible of cmbodimentin various forms all coming within the scope of the claims which follow.
